2
which step should I take
Answers
Answer:
Divide both sides by V
Step-by-step explanation:
The equation is not well written.
Mariko needs to solve the equation below for D. Here is the equation:
M = DV
For Mariko to get D, he needs to make D the subject of the formula by dividing both sides of the equation by the coefficient of D i.e V as shown;
Divide both sides by V
M/V = DV/V
V at the denominator will cancel out the V at the numerator to have:
M/V = D
Rearrange
D = M/V
Therefore, the statement which correctly describes the step he should take is:
Divide both sides by V. Option B is correct.

The value of x after eliminating the variable y is -9.
What is an elimination method?The elimination method involves taking one variable out of the system of linear equations by using addition or subtraction along with multiplication or division of the variable coefficients.
Given that the two equations are 9x – 2y = – 75 and 2x – 2y = -12. The equations will be solved as,
9x – 2y = – 75
2x – 2y = -12
The value of x will be calculated by elimination of the variable y,
9x – 2y = – 75
-2x + 2y =+12
_____________
7x + 0 = -63
x = -9
Therefore, the value of x after eliminating the variable y is -9.

What is the product of two odd numbers and a multiple of 2
Answers
An odd number is (2x) + 1
An even number is (2x)
These are the definitions.
Using the binomial (2x + 1)(2x + 1), we can see the properties of all products made from odd numbers.
Foiling will give 4x^2 + 4x + 1.
4x^2 is even because 4x^2 can be expressed as 2(2x) x 2(2x).
4x is even because 4x can be expressed as 2(2x)
This means that 4x^2 + 4x is even so the expression 4x^2 + 4x + 1 is odd because an even number + 1 is odd as shown by (2x) + 1.
This shows that every outcome of the product of 2 odd numbers will result being odd.
This means there is no answer to this problem, because any number that is a multiple of 2 is even. (Basically the definition of even)
Using even and odd numbers concepts, it is found that the product is an even number.
------------------------
An even number is a number that is divisible by 2.An odd number is a number that is not divisible by 2.------------------------
The product of two odd numbers will always generate an odd numbers, examples: [tex]3 \times 5 = 15, 3 \times 7 = 21, 3 \times 9 = 27[/tex]The product of an even number with an odd number will always be an even number, as examples: [tex]3 \times 4 = 12, 3 \times 6 = 18[/tex]------------------------

The number that rode in columns was 3 2/3 times the number that rode in rows. If 2200 rode in columns, how many rode in rows?
Answers
Answer:
600
Step-by-step explanation:
Given parameters:
Number that rode in columns = [tex]3\frac{2}{3}[/tex] times the number that rode in rows.
2200 rode in columns
Unknown:
Number of people that rode in rows = ?
Solution:
Let the number of people that rode in columns = C
Let the number of people that rode in rows = R
C = [tex]\frac{11}{3}[/tex]R
Number of people that rode in rows = 2200;
2200 = [tex]\frac{11}{3}[/tex]R
11R = 2200 x 3
R = [tex]\frac{2200 x 3}{11}[/tex]
R = 200 x 3
R = 600
Number of people that rode in rows = 600

What is Binomial Distribution?
Number of trials or observation when each trial has the same probability of attaining one particular value. It determines the probability of observing a specified number of successful outcome in a specific number of trial.
Here , number of times the coin had tosses: 100
P(probability of getting a head in a coin ) : number of time head can come when flipped once / total number of observations
since , head can come once and there are two possibility either head or tail
hence P= 1/2
this implies number of times heads land up = n*P = 100 *(1/2) = 50
option c) 50

Answers
Answer:
Option (D) is correct
Step-by-step explanation:
If y is a multiple of x and versa, it will have a constant of proportionality.
Option (A)
y = (81/3)xy
y will cancel out
1=27x
It is not correct
Option (B)
y=9xy
y will cancel out
1=9x
Option (C)
y=3xy
y will cancel out
1=3x
Option (D)
y = (1/9) x
y will cancel out
x=9y
In option (D), we see that x is 9 times of x. It means it has constant of proportionality equal to 9.
The equation y = 9x represents the constant of proportionality which is equal to 9.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation can also be used to represent direct proportionality as -
y = mx
m = y/x
[m] is called constant of proportionality
We have the constant of proportionality equal to 9
The equation y = 9x represents the constant of proportionality which is equal to 9 as when compared with y = mx, we get m = 9.
Therefore, the equation y = 9x represents the constant of proportionality which is equal to 9.

-2.5°F ___ - 1.9°F _____ 0°F _____ - 1.5°F _0.5°F
Days colder than - 1.75°F
Days colder than - 1.75°F are days whereby the temperature value is less than - 1.75
Hence,
-2.5°F < - 1.75°F = (Monday)
-1.9°F < - 1.75°F = (Tuesday)
